TWO-ROW DISK CULTIVTOR.

SPECIFICATION forming part of Letters Patent No. 722,235, dated March 10, 1903.

Application led September 9, 1902. Serial No. 122,687. (No model.)

To all whom it' 77u07/ concern,.-

Be it known that I, LINDEN KIRLIN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Two-Row Disk Cultivators, of which the following is a specication.

My invention relates to improvements in two-row cultivators; and one of my objects is to relieve the shovel-beams of the severe strains incident to the shovels passing through rough and uneven ground by interposing a yielding connection between said shovelbeams and the operating-levers.

A further object is to mount said levers in such a manner that the driver may conveniently operate them without leaving his seat when it is desired to raise or lower the cultivating appliances.

Another object is to provide a rigid and compact frame which, while dispensing with unnecessary material, is well adapted to resist the various strains to which a machine of this character is subjected when operating in the field.

Referring to the accompanying drawings, which illustrate my invention, Figure 1 represents a plan view of one of the gangs forming part of the machine with a portion of the seat-plank broken away. Fig. 2 is a vertical section of the same, taken on line II II of Fig. 1. Fig. 3 is an enlarged detail perspective View of one of the standards. Fig. 4 is abroken detail perspective of one of the trusses. Fig. 5 is a broken detail side view of the upper end of one of the crank-arms.

In practice I prefer to employ two gangs connected in the usual way by a seat-plank, and as the gangs are duplicates I have, for convenience, shown but one in the drawings, which I will now proceed to describe. In constructing said gang I employ a front and rear bar 1 and 2, respectively, the former of which is provided at its'opposite ends with standards 3 3f, secured thereon by bolts 4. Said standards have depending lower portions 5, which fit snugly against the opposite sides of bar 1 and relieve the bolts to a large extent of the bending strains to which they are subjected. The standard on the inner side of the gang is provided with an integral vertically-extending arm 6, terminating in an oblique end 7, adapted to receive the forward end of a longitudinal bar S, secured thereto, which extends rearwardly and is secured to the oblique upper end 9 of a vertical arm 10, formed integral atits lower end with a standard 11, secured upon the rear bar 2 by a bolt 12. Said standard is provided with a front depending portion 13, which fits snugly against the side of bar 2, and a rear bearing 14C, which fits snugly against the rear side of said bar, and it tapers at its upper end to receive the inner end of a longitudinal channel-bar 15, supported at its opposite end by a standard 11, similar in form to standard 11 with the exception that arm 10 is dispensed with. The upper ends of standards 3 3a are also connected by a channel-bar 15, held thereon by two transverse rods 16, the opposite ends of which rest upon the rear chan nel-bar. With the ends of the transverse rods and channelbars thus arranged and secured together by bolts 4, 12 itis obvious that I have obtained a very substantial and rigid frame. The frame as thus constructed is supported by a pair of trusses 17, the opposite ends of which underlie bars 1 and 2 and are provided with eyes 18 to receive bolts 19, arranged on opposite sides of the bars and which extend up through plates 2O and are adjustably secured by nuts 21 in order that the trusses may, if desired, be adjusted laterally on the bars or arranged with their forward ends converging in the Well-known manner. rPhe lower horizontal portions 22 of the trusses have series of holes 23 for the adjustment of carrying-wheels 24 either forwardly or backwardly to maintain the equilibrium of the machine when the seatplank is adjusted to the frontor rear portion of the frame. The rear bar 2 is of greater length than bar 1 to provide a wide range of lateral adjustment for disk-arms 25, secured thereto by bolts 26, and provided at their rear ends with disks 27, adjustably arranged so they may be set to throw the soil toward or away from the plants in the well-known manner.

28 indicates a shaft journaled in bearings 14 to receive shovel-beams 29, adj ustably secured thereto by set-screws 30 and provided at their lower rear ends with shovels 31.

32 is a crank-arm secured to shaft 28 adjacent to inner bearing 14, and said crank-arm is provided at its upper end with an aperture 33 to loosely receive the rear portion of a connecting-rod 34, which extends forwardly and upwardly and is pivotally secured to a handlever 35by bolt 35a. The rear portion of rod 34 is retained in aperture 33 by a pin 36 and is provided with an expansion-spring 37, interposed between the crank-arm and a pin 38 to provide a yielding connection between the crank-arm and the hand-lever. Spring 37 is stiff enough to hold the shovels down in ordinary soil, but will yield before the shovels encounter sufficient resistance to bend or break the shovel-beams,and I have found bypractice that the springs are much more reliable for this purpose than the break-pins usually employed. When a rigid connection is desirable, pin 36 is removed from rod 34, and the latter is pushed forward until the pin-hole therein registers with a pin-hole 39 in the crank-arm. Pin 36 is then inserted in the pin-holes, and the expansion-springs of course become inoperative.

Hand-lever 35 is fulcru med at its lower end on a bolt 40, extending through longitudinal bar 8 and a notched segment 41 secured to said bar and adapted to be engaged by a latch 42, operatively secured to the hand-lever for the purpose of locking the latter at any desired position. The segment and hand-lever being secured to the inclined side of longitudinal bar 8 extend upwardly at an angle, so the handles of the lever may be conveniently reached by the driver while occupying the seat 42 on seat-plank 43. Said seat-plank is adjustably secured upon transverse rods 16 by loop-bars 44 and may be adjusted forwardly or backwardly by a chain 45, loosely embracing a loop-bar 46, and adapted to be adjustably secured at its opposite ends to hooks 47, pivotally secured on the channelbars 15.

Each gang is provided with a tongue 48, suitably secured to bars l 2 for the purpose of balancing the machine and also to provide means for bitching teams to the gangs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cultivator comprising two gangs secured together by a seat-plank, longitudinal bars secured above 'the seat-plank to the gangs, hand-levers pivotally secured to said longitudinal bars, means for holding the levers in any desired position, connecting-rods pivotally secured at their forward ends to the hand-levers, cran k-arms to which the opposite ends of the connecting-rods are operatively secured, journaled shafts to which the crankarms are secured, and suitable cultivating appliances carried by the journaled shafts, substantially as described.
